SLATE-WASH ER.

SPECIFICATION forming part f Letters Patent No. 255,851, dated April 4,1882.

Application filed August 24, i881. (No model.)

Beit known that we, WALTER B. GROSS and JOHN S. GEORGE, citizens of theUnited States, and residents ofBrid geport, in the county of Fairfieldand State ofGonnecticut, have invented a new and useful Improvement inSlate-Washers; and we do hereby declare the following to be a full,clear, and exact description of the invention, which will enable othersskilled in the arts to which it appertains to make and use the same.

Theiobject ot' our invention is to provide a simple, neat, and portableslate-washer consisting of an inner shell operating as a reservoir forthe water, a sponge attached to the mouth of the inner shell, an outershell surrounding the inner shell or reservoir, arranged and adaptedtoslide longitudinally on the inner shell and inclose and protect thesponge when not in use.

Heretofore slate-washers have been constructed with a sponge attached toand projecting from the reservoir; but the sponge is unprotected and isliable to leak, and is therefore unfit to be carried in the pocket.Slatewashers have been constructed having two parts capable of beingdetached. The part" holding the sponge is reversed and inserted within acavity in the lower part. This is objectionable in view of the fact ofits being used mostly by children, and in two parts oneor the otherisliable to get lost; In our improved slate-washer the outer shell,sliding freely on the inner shell, is made to project over and inclosethe sponge. A pin attached to and projecting from the surface ot' theinner shell engages with a groove in the outer or sliding shell,thus'preventing any ofthe parts becom- 1 ing lost.

To more clearly understand our invention reference is had to theaccompanying drawings, in which- Figure l represents a View of thewasher complete, the sponge exposed and ready for use. Ais the outer orsliding shell, and is provided with the groove a. B is the inner shellor reservoir 'for holding the water. C represents the upper part of theshell B, tapered to assist in holding the sponge in place. D isthesponge. E is the stopper in the other l end giving access lo theinterior ofthe reservoir. b is a pin projecting from the surface ot' theshell B, which engages with the slot or groove a of the outer shell andprevents its dropping olf.

Fig. 2 is a view representng the outer or the sponge D.

the manner of securing the sponge within the inner shell, B. c is arubber disk closely titting the interior of the shell B, and to which isattached the sponge D. d is an aperture, through which the water passesto the sponge.

I's construction and operation are as follows:

The shells A and B are preferably coilstructed of sheet metal drawn inthe proper shape. The end O ot' the inner shell, B, is tapered to holdthe sponge 1) in position. The sponge D is rst attached `to the rubberdisk c (see Fig. 3) and inserted in the opposite end, c, of the shell B,and forced upward until the disk c meets the inclined sides ff of thetaper end O. rlhe sponge is crowded through and projects from the endofthe shell the proper distance required. The sponge is thus held firmlyand securely in place.

The disk c is provided with the hole d, through which the water in theinterior of the reservoir g reaches the sponge. The stopper E is removedwhen necessary to till the reservoir, and is preferably made of rubberto serve the purpose of a lead-pencil eraser, as well as being the bestmaterial to retain its position at the mouth of the reservoir, and isalso impervious to water.

The outer shell, A, is intended to slide freely over the inner shell, B,and is prevented from slipping off by the pin b, attached to the shellB, engaging with the slot d ofthe sliding shell A. When the shell A isforced upward toits full limit (see Fig. 2) it is turned to the left,the pin b entering and resting in the transverse sloth, which is acontinuation of the perpendicular slot a, thus preventing the slid down.

A slate-washer constructed as above described is easily operated,compact in form,

sliding shell, A, pushed forward and inclosing` ing shell A from beingaccidentally forced Fig. 3 is a sectional view ot Fig. l, showing IOOand can be carried in the pocket with perfect safety, making aconvenient Iand useful article for the purpose required.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is-

o The combination, with the shell B, having tapering end C, sponge D,disk c, reservoir g,

stopper E, and pin d, of the sliding shell A,

havingslotsa and h, substantially as described, and for the purpose setforth.

In testimony that we claim the foregoing We have set our hands in thepresence of two subscribing Witnesses.
